SEPARATING PARTICLES BY HORIZONTAL DEFLECTION IN A PARAMAGNETIC FLUID

摘要

This paper describes the horizontal deflection behavior of particles in paramagnetic fluids under a highgradientrnsuperconducting magnetic field. Movements of single particle were observed experimentallyrnand indicated that they could be deflected to different positions. Based on these results, the behaviorrnof groups of particles from ore samples was examined in the superconducting magnetic. It was foundrnthat these particles could be deflected and settled at a certain position due to the combination ofrngravity and magneto-Archimedes forces as well as a lateral buoyancy (displacement) force. Mineralrnparticles with different susceptibilities and/or densities could be deflected to different positions, thusrnproducing groupings of similar types of particles. The work described here, although in its infancy,rncould form the basis of new approach to separating particles based on a combination of susceptibilityrnand density.
